Abstract

A supply-to-digital regulation loop (SDRL) circuit, including a reference supply circuit and a local supply circuit. The reference supply circuit includes a reference supply-to-digital converter (SDC) to convert an analog reference supply voltage to a digital reference signal. The local supply circuit is coupled to the reference supply circuit. The local supply circuit includes a local SDC to convert an analog local supply voltage to a digital local supply signal based on a digital feedback signal, and a local monitoring circuit to monitor the digital feedback signal based on a comparison of the digital local supply signal with the digital reference signal routed from the reference SDC of the reference supply circuit.
